"Wikipedia is a gold mine of lists, lists of lists and even lists of lists of lists. One of these lists of lists happens to be Billboard’s Hot 100 songs which allows us to browse Wikipedia’s data pretty easily."

"Each graphic represents the history of a single article. Time moves from left to right. The varying heights of the coloured section of represent how many lines an article had at each point in time. Articles typically start short and become longer over the years."

"Histography is interactive timeline that spans across 14 billion years of history, from the Big Bang to 2015. The site draws historical events from Wikipedia and self-updates daily with new recorded events."

"While Wikipedia is a most modern creation, its content reflects a historical accumulation of facts and attention. This map of London shows the density of articles in Wikipedia associated with locations in London."

"Taha Yasseri of the Oxford Internet Institute and colleagues looked at Wikipedia’s different language editions from their inception (January 2001 for English) to March 2010 and ranked the most contested articles, based on the number of reverts and the number of edits the contributors have made (dubbed their “maturity score”)."

"Here we use the structure of the networks connecting multilingual speakers and translated texts, as expressed in book translations, multiple language editions of Wikipedia, and Twitter, to provide a concept of language importance that goes beyond simple economic or demographic measures."

"The motivation of this page is to get a little more oversight of the facts and connections which are part of the Wikipedia. To get the birds eye view of Wikipedia we have to focus a part of of the whole we want to focus. This focus should describes a field of articles that interrelate."

"...I wanted to get a picture not only of what Wikipedia articles pointed at the Paris Review, but also Paris Review interviews which were not referenced in Wikipedia. So I wrote a little crawler that collected all the Paris Review interviews, and then figured out which ones were pointed at by English Wikipedia."

"These links indicate individuals who have co-edited many pages together on Wikipedia. We use a custom weighting technique, and filter down to the core editors (in every language except Egyptian Arabic and Swahili where we use everyone). The fact that this core is so well connected indicates the coherence of the Wikipedia community."

"At the global scale (in an article that we currently have under review), we found that the number of Wikipedia articles within (or describing) a country can be explained to a large degree by just three factors: (1) the size of its population, (2) the number of its fixed broadband internet connections, and (3) the number of edits committed to Wikipedia by its population."

"I am a highly visual person. When I have to learn something new, I usually first try to make a sketch of the structure of the knowledge that I want (or have to ;-)) to study. This usually results in diagrams outlining the material, giving it some structured form that makes it easier for me to grasp. "

"In this case the nodes in the network are wikipedia articles and the edges are the links between articles. We then ... used an algorithm to lay out all 650,000 nodes (wikipedia articles) that had at least one link in such a way that similar articles are near one another. These are the yellow dots, which when viewed at low res give a yellow tint to the whole picture."

"First, this study introduces the Flow Circle, which is a new exploratory data analysis tool devised to solve such problems of History Flow. Second, this tool is used to actually visualize the Wiki revision history regarding gun politics in order to understand and analyze the flow of the revision history and the relationship and conflict structures between the authors based on the results of the MDS analysis."

"The clustering component of this visualization is vital. The mere presence of information isn't all that interesting; there is no context or relevance to be gleaned. However, the structure of information is revealing about where fields intersect and diverge, and ultimately about how humans organize information."

"We analyzed and visualized Article for Deletion (AfD) discussions in the English Wikipedia. The visualization above represents the 100 longest discussions that resulted in the deletion of the respective article. "

"Since geography is never far from history, a lot of maps show the colonial past of many countries. As ethnic groups don’t always fall inside political borders, several maps reveal the presence of multiple ethnic or cultural groups within a country or of groups stretching across borders."

"Wikistream is a Node.js webapp for helping visualize current editing activity in Wikipedia. It uses Node.js, socket.io and Redis to sit in the wikimedia IRC chat rooms (where updates are published), and makes them available on the Web in realtime."
